People who post their spam links as comments on weblogs make me angry, but only a little bit. What REALLY makes me angry, is the attempt at pretence of a real comment, for example - 'I really loved your blog, keep up the good work! Check out http://www.notverygoodsoftpornoforsale.com'.
This is not only spam, but a direct insult to someones intelligence. They should stick to - 'We're sorry we've spammed you, but that's our job, hopefully you won't notice this link at all, and we'll drive traffic to our porn site - http://www.notverygoodsoftpornoforsale.com. Regards, Mr. Spammer '
A bit of honesty goes a long way.
